Looking for suggestions - "Digital Spacefoam"

Heyyo, I'm looking for a bit of design advice on this next graphic. The pattern is simply because I wanted to make a pixelated shirt that didn't look like camouflage, but it's missing a concept. I'm guessing a cubic Earth, animal, a pixilated tree might give it some narrative, but it's just kind'v there, still. Whaddya think? Has this been done to death?
